She has scars from where she says a student scratched her and memories of a student beating her chest when he didn't get his way.

Brockman says she even had an orange thrown at her head while driving down the road.

"Because they can get away with it. They can do whatever they want. They have no respect for older people," Brockman said.

Lee County School Board member and bullying education advocate Mary Fischer says incidents like the one caught on tape happen when students see an easy target.

"The status in the group is a very important thing, and they were picking on someone who is basically not part of their group, an older person. It's that group mentality, that mob mentality that happens especially to those people who are trying desperately to be part of the group," Fischer said.

Lee County School officials couldn't speak to specific incidents on their buses, but according to school policy, anything that interferes with student safety including profanity or abusive language will not be tolerated.

Fischer says before school starts next fall, all district employees will undergo bully training to help curb the problem.
